Here's an interesting observation.
I know about 6-8 self identified CD's personally and pretty well. Most of them have been to my house at least twice and I've been out with all of them countless times. I have never heard a single one of them complain about the world not accepting them. Perhaps there's a correlation between being closeted and thinking the world is against you.
You can't make the world accept you, but you can certainly be accepted in YOUR world. If you are closeted because your friends won't accept you, then you're part of the problem.
